Title Reproductive Response of Soybeans to Night Interruption1 Type Journal Article
Year 1981 Publication Crop Science Abbreviated Journal (up)
Volume 21 Issue 5 Pages 755
Keywords Plants
Abstract Artificial lights may be used to delay flowering of soybean [Glycine max (L.) Merr.] cultivars. Previous research has suggested that night interruption imposed every other night would delay flowering as much as every-night interruption. Our objective was to evaluate the reproductive development of cultivars when exposed to night interruption every night compared with exposure every other night. One cultivar of each Maturity Group 00 through V was grown in the field at Ames, Iowa during 1978 and 1979. The four light treatments imposed every night or every other night included illumination with incandescent light from sunset to sunrise, 2300 to 0030 hours, 0030 to 0200 hours, or 0200 to 0330 hours. Control plots were not exposed to artificial light.

The average number of days that reproductive development was delayed beyond the control was twice as great for the every-night treatments as for the every-other-night treatments. Illumination from sunset to sunrise delayed reproductive development significantly more than the treatments of night interruption for 1.5 hours. Night interruption near the end of the dark period (0200 to 0330 hours) delayed reproductive development more than the earlier interruptions.

The results did not support the hypothesis that light treatments every other night would delay reproductive development as much as every-night interruptions. The lighting regime needed to delay reproductive development will depend on the photoperiod requirements of the cultivars and duration of the delay that is desired.

Title Measurement of Light Pollution Type Journal Article
Year 2014 Publication Methods of Measuring Environmental Parameters Abbreviated Journal (up)
Volume Issue Pages 368-370
Keywords Skyglow
Abstract Digital photography is based on the conversion of light by sensitive matrix (array of electronic photodetectors) to capture the image which is then digitized and stored as a computer file for further processing and printing. The spectral sensitivity of the cameras is in good agreement with the spectrum of action of the photosensitive hormone melatonin. Digital photography can be used to quantify light pollution acting on the physiology of living organisms. The chapter discusses the principles of spectrophotometry. A portable spectrophotometer for the measurement of light pollution is proposed by Cinzano. It consists of a cooled CCDcamera and a small spectrographic head which is equipped with a De Amici prism composed of two external crown prisms and an inner Flint prism. Sky quality meter (SQM) is a portable photometer for measuring sky brightness and for light pollution monitoring. This device collects the light from a wide solid angle.

Title NixNox procedure to build Night Sky Brightness maps from SQM photometers observations Type Report
Year 2014 Publication E-prints Complutense Abbreviated Journal (up)
Volume Issue 26982 Pages
Keywords Skyglow; measurement; SQM; SQM-L; mapping
Abstract The NixNox procedure to build all-sky maps of the nocturnal night sky brightness using SQM photometers is described. Astronomers belonging to amateur associations in Spain are using this observational method to obtain data of their preferred sites of observation to characterize the astronomical quality of the sky and the sources of light pollution.
